AcidFly has a point. As a rabid fan of tutorials, both purchased and free, I have to say that (like most anything else) they are not created equal. The vast majority are awesome, superbly done and well written/photographed. Some, well....eh...not so much - but fortunately these are rare. An experienced lampworker usually has a pretty good idea of what is going to be required to work the tutorial before purchasing - but an inexperienced one may not and the suggestion of materials required up front is a good one as well as an honest assessment of the skill level required for the technique. As far as cost to the lampworker goes, I am always willing to pay a little more to compensate an expert who is taking their precious time away from their craft to educate me.
